8 Claims. (Cl. 12S- 283) This invention relates to a colostomy or related device, of the type designed to be secured in position against a colostomy opening formed in the human body to receive4 excrement or other matter discharged from the body. Like other devices heretofore designed for this purpose, it comprises an annular disc or plate designed to be secured with its inner face lying against the body in surrounding relationship to the opening, and a bag secured to said disc in position to receive excrement discharged therethrough.

An object of this invention has been to provide an apparatus of this kind which may be worn with a minimum of discomfort to the user, when either awake or asleep.

A further object has been to provide such an apparatus with attachments and a combination of parts insuring that the bag will remain open to receive excrement at all times.

A further object has been to provide, in the colostomy device, a combination of parts arranged for relatively easy separation for cleaning and replacement.

A further object has been to provide such a combination in which the parts are constructed and interconnected in such a way as to provide maximum insurance against fouling.

Still further objects and advantages, and the manner in which they have been attained, will be evident from reading of the following detailed description in the light of the attached drawing, in which:

Figure l is a view of the assembled colostomy device, as attached to the human body; i

Figure 2 is a cross-section on the line 2-2 of Figure 1; and

Figure 3 is a perspective View, illustrating the individual parts in the order in which they may be secured together.

As in prior colostomy devices designed for this purpose, the primary elements of the device consist of the annular disc or plate 10, a bag 11 of polyethylene plastic or the like detachably secured to that disc in surrounding relation to its central opening, and connections and associated parts for securing these members to each other and to the human body. The characteristic aspects of the invention are the features by which the above-mentioned objects are attained in the specific construction and interconnection of these parts.

As illustrated in the drawing, the disc is provided with a tubular neck 12 extending longitudinally at its outer face and a laterally outwardly extending flange 13 is formed at the outer end of this neck, to coni-ine the upper end of the bag and the means for securing the device to the body of the user, a second annular disc 14 is mounted about the neck 12 as illustrated in Figure 2, and this disc is provided with laterally extending lugs or ears 15 for attachment to a belt 16 through snap fasteners or equivalent detachable connections 17, the belt being worn about the waist of the user with the parts in place as illustrated in Figure l.

The two discs may be formed of any suitable flexible and resilient material, such as a synthetic rubber, an acrylic resin or other material capable of providing the ,d necessary resiliency while resisting chemical deterioration, and it is possible to install the disc 14 in the position illustrated in Figure 2 surrounding the neck 12 of the disc 10 because of the inherent flexibility of the flange 13 which permits it to be bent to permit this installation. The upper end 18 of the ilexible bag 11 is secured about the neck 12 between the ange 13 and the outwardly extending portion of the main body of disc 10 by means of an elastic annulus 21 which may be in the form of a tension coil spring bent annularly and having its opposite ends secured to each other through a handle 22. It will be seen that by bringing the upper end of the bag into position surrounding ange 13 as illustrated in Figure 2,

' and thereafter securing the coil spring in place by manipulation of its handle 22, the bag 11 may be secured in fluid-tight relationship to the disc 10.

ln addition to the disc 10 which forms the basic structural member of the device andthe disc 14, which serves for securement of the device to the person of the user, there is provided a third annular disc 19, which may be formed of very thin flexible material capable of resisting perspiration and discharges received through the device, and this disc may be made of polyethylene plastic or equivalent material. The central portion of the disc 19 is preferably an outwardly projecting tubular extension as indicated at 2i), so that only the body portion of the wearer against which the device is pressed may be protected by this shield 19, but also the colostomy stub through which the device receives its discharges.

In order to insure that the device will always be free of pinching, i. e., that the folds of bag 11 may not be closed against each other so as to prevent passage of eluents to the lower end of the bag, the lower side of ilange 13 is grooved as illustrated in Figures 2 and 3 to provide one or more downwardlyextending drainage channels 23 on the outer side of this end portion of the ilange, and this part of the ange is laterally enlarged, as also illustrated in these figures. VIt will be seen that the projecting side walls 24 and the intermediate ridges of these channels tend to maintain the channels open by preventing the opposing side of bag 11 from entering this space. As a further measure to maintain the bag fully open, at least at its upper end, there is provided an abutment structure in the form of a Wire framework projection 26, which is secured to the outer face of the neck 12 as illustrated to hold the outer side of the upper end of the bag away from the main body of the colostomy appliance, as illustrated in Figure 2.

It should be noted that both the protective disc 19 and the bag 11 are made of relatively thin ilexible material, and may beV disposed of very easily and replaced at small expense. Thus, while these members have the advantage of resistance to moisture andchemical attack, 'it is the intention that the bag 11 be replaced as often as may be necessary, and that the protective disc 19 also be frequently replaced.- The making of the other parts of the apparatus as a number of separableelement's is also of considerable advantage in this type of device in that it facilitates cleaning and replacement of any of the parts individually as need may arise.

While I have described only a single embodiment of the invention, persons skilled in the art will be aware that it may be. modiied in various ways without departing from its generic scope, and I therefore wish it to be understoodthat lthis invention is not to be limited except by the scope 'of the following claims.
